However, in our own study, we found very little evidence of enrichment for imprinted genes.

Our findings do not support the hypothesis that paternal BMI around the time of pregnancy is associated with offspring-blood DNA methylation, even at imprinted regions.

Invasive meningococcal disease (IMD) is an acute, highly transmissible and potentially fatal disease caused by Neisseria meningitidis. Prompt antimicrobial therapy and prophylaxis are recommended, where penicillin or ciprofloxacin are the available choices. However, the emergence of resistant isolates of N. meningitidis poses a challenge for antimicrobial therapy.

To describe the clinical, epidemiological and biological characteristics of six penicillin- and ciprofloxacin-resistant, culture-confirmed IMD cases reported in El Salvador, Central America, between 2017 and 2019.

Following the detection of six patients presenting with IMD in El Salvador, clinical data were collected and epidemiological action plans conducted. Isolates were subjected to antimicrobial susceptibility testing by broth microdilution and WGS for genotyping and molecular characterization analysis, including phylogeny comparison with global sequences available from public databases.

A total of six IMD cases caused by N. meningitidis serogroup Y, resistant to both penicillin (MIC >8.0 mg/L) and ciprofloxacin (MIC 0.125 mg/L), were detected from 2017 to 2019. Genomic analysis showed that penicillin resistance was mediated by the production of β-lactamase ROB-1. Ciprofloxacin resistance was attributed to an amino acid substitution in DNA gyrase (T91I). All isolates were classified as ST3587, clonal complex 23, and were genetically highly similar, based on core-genome SNP analysis.

To the best of our knowledge, we report the first cases of MDR N. meningitidis causing IMD in Latin America. Our findings highlight the emergence of this potential public health threat, with a profound impact on the efficacy of IMD treatment and prophylaxis protocols.

This is an extremely rare location, and most of patients are asymptomatic.3-6 Signs of compression of the seventh and eight cranial nerves can be present and even Horner syndrome and lower cranial nerves neuropathies. Nevertheless, rupture can lead to epistaxis and otorrhagia, and ultimately to hemorrhagic shock. The patient in the current report was otherwise healthy but presented with lightheadedness and dizziness for 10 d. The patient consented to the procedure. There was no history of major trauma or head and neck infection. A transradial endovascular flow diversion embolization of a giant aneurysm of the petrous internal carotid artery is herein demonstrated in a stepwise manner. A triaxial system was used to deploy 3 overlapping devices. Concepts of J-wire technique, multiple coverage,1 and the so-called weld technique are emphasized. The role of adjunctive coiling and main reasons for failure are also discussed.7,8 Brief cases of flow diversion embolization of aneurysms of different morphologies at different locations are used to highlight the importance of assessing vessel wall apposition and follow-up imaging.Although variables are often measured with error, the impact of measurement error on machine learning predictions is seldom quantified. The purpose of this study was to assess the impact of measurement error on random forest model performance and variable importance. learn more First, we assessed the impact of misclassification (i.e., measurement error of categorical variables) of predictors on random forest model performance (e.g., accuracy, sensitivity) and variable importance (mean decrease in accuracy) using data from the United States National Comorbidity Survey Replication (2001 - 2003). Second, we simulated datasets in which we know the true model performance and variable importance measures and could verify that quantitative bias analysis was recovering the truth in misclassified versions of the datasets. Our findings show that measurement error in the data used to construct random forests can distort model performance and variable importance measures, and that bias analysis can recover the correct results. This study highlights the utility of applying quantitative bias analysis in machine learning to quantify the impact of measurement error on study results.
Although female sex workers (FSWs) have long been identified as a key human papillomavirus (HPV)-affected population, the burden and scope of their disproportionate risk for HPV infection have not been systematically estimated. We therefore aimed to estimate the prevalence of HPV and the distribution of HPV types in FSWs at the country, regional and global levels.

We searched the PubMed, Embase, SCOPUS, EBSCO, ProQuest, Cochrane Library and Web of Science databases for articles published between 1 January 1990 and 31 June 2019. Studies of genital HPV prevalence in FSWs, or with sufficient data (e.g. adequate number of HPV-positive cases and sample size) to compute prevalence rates in FSWs, were included in this systematic review. The meta-analysis was completed using the random effects model.

We ultimately identified 107 studies in 45 countries or regions with sufficient data to calculate HPV prevalence in FSWs. The pooled global HPV prevalence among FSWs was 39.5% (95% CI 35.3, 43.9%), with notable variations by WHO region and country. Globally, the five most common HPV types in FSWs were HPV16 (9.0%), HPV 52 (8.3%), HPV89 (7.0%), HPV58 (6.2%), and HPV53 (5.3%).

Our findings suggest that FSWs are disproportionately affected by HPV, which is more pronounced in the Western Pacific and African regions, and are therefore in need of prevention, treatment and care services.
